Theory Questions
Write short notes on the following: 2003, 2007- June |8|
(b) Direct expense
Answer:CIMA has defined direct expenses as direct expenses are those expenses which connote be identified
with and allocated to cost centers or units. Thus, they are directly identifiable and chargeable to a
product process, job, contracts and service. They form major part of prime cost. Example: Cost of patent
rights, hire charges of special plant, experimental cost, Royalty paid in mining, costs of special layouts
and designs, etc.

(b) Pre-requisites for computerization of accounts
Answer:
Today Computerization of accounts is a necessity as it has many advantages.Advantages:
1. It can store large volume of data.
2. It can do arithmetic and logic operation more quickly.
3. It can store past records for infinite life.
4. It always gives accurate results without human intervention.
(Garbage in garbage out)
But for proper working of computer it is necessary to feed correct and complete data in computers. If the
data is incorrect or incomplete the result will be misleading.
Pre-requisite:
Proper coding system for various departments, products, raw materials, etc.
Basic documents like GRN, MTN, time card, job card, MRN, etc
Reconciliation of cost and financial accounts.

Profit Centre
Answer:Profit Centre: Profit centre is a responsibility centre for which both costs and revenues are
accumulated.As defined by CIMA, London profit centre a part of business accountable for costs and revenues
It may be called a Business Unit or Strategic Business Unit. The object of profit centre is to maximize the
centres profit i.e. difference between revenues and expenses.

(a)Economic Oder Quantity (EOQ)Answer:
Quantity for which order is placed when stock reaches re-order level.
The optimum level will be that quantity which minimizes the total cost associated with inventory.
The optimum size of the order for an item is known as Economic order Quantity (EOQ)and is
calculated so that total inventory costs are at a minimum for that particular stock item.

(b)Obsolescence
Answer:Obsolescence: It means sudden loss in value of the asset as it needs to be discarded before the expiry
of its normal life due to one or more of the following reasons.i. Change in the technology
ii. Discontinuance of the product line
iii. Introduction of a new machine
iv. Change in production specification
Obsolescence is not treated as overhead expenses and is charged to Profit & Loss Account directly
because obsolescence loss is an abnormal loss.
Write short notes on the following: 2009-Dec |8|
(a)perpetual Inventory System:
Answer:
Perpetual Inventory System:Perpetual Inventory system mean continuous stock taking. Under this system, a continuous record of
receipt and issue of materials is maintained by the stores department and the information about the stock
of materials is always available. Entries in the Bin Card and the Stores Ledge are made ager every
receipt and issue and the balance is reconciled in regular basis with the physical stock.
The main advantage of this system is that it avoids disruptions in the prediction caused by periodic stock
taking.
Similarly this system helps in having a detailed and more reliable check in the stocks. The Stock records
are more reliable and stock discrepancies are investigated and appropriate action is taken immediately.

(a)Treatment of scrap in cost accounts;
(d)VED Analysis;
Distinguish between Scrap. Spoilage and Defectives in engineering in an engineering
industry. 2009-Dec |2|
Answer:Scrap is a residual material resulting from a manufacturing process. It has a recovery value and is
measurable. Its treatment in cost account will depend on the total value of scrap.
For the control purposes, scrap could be divided into: legitimate scrap, administrative scrap and defective
scrap.
It can be controlled through selection of right type of material and manpower, determination of acceptable
limits of scrap and reporting the source or waste.
Spoilage is the production that fails to meet quality or dimensionalrequirements and so much damaged
in manufacturing operations that they are not capable of rectification and hence has to be withdrawn and
sold off without further processing. Rectification can be but its costs may be uneconomic.

P a g e |5Defective: are a part of production units, which do not conform to the standards of quality but can be
rectified with additional application of material, labour and / or processing and made it into saleable
conditions either as firsts or seconds, depending upon the characteristics of the product.
The accounting treatment of defectives is same as those of spoilage.
Thus the difference between scrap, spoilage and defective is very subtle.
In some engineering units, even they are all clubbed under one head
Explain the term Economic Ordering Quantity (EOQ). What are the basic assumptions of
EOQ model?2001-Dec |2|
Answer:Economic Order Quantity
Re order quantity or Economic order quantity
Quantity for which order is placed when stock reaches re-order level.
The optimum level will be that quantity which minimizes the total cost associated with inventory.
The optimum size of the order for an item is known as Economic Order Quantity (EOQ) and is
calculated so that total inventory costs are at a minimum for that particular stock item. Ordering cost includes preparation of purchase order, cost of receiving goods, transport cost,
etc.
Carrying cost includes storages cost, insurance & security cost, handling cost, etc.
EOQ=
Where, EOQ=Economic Order Quantity
A= Annual Consumption
B= Buying cost per order
C= Cost per unit
S= Storage and other inventory Carrying Cost in percentage
Basic Assumption of EOQ Model:-
The calculation of EOQ presumes that:-
There is a known stock-holding cost
There is a known constant ordering cost.
The rates of demand are known and constant
Constant price per unit is known
Replenishment is made instantaneously,
What are the implications of Economic Order Quantity in proper inventory management?
2007-Dec |4|
Answer:Inventory control is concerned with minimizing the total cost of inventory. The three main factors in
inventory control decision making process are:
The cost of holding the stock (e.g., bases on the interest rate).
The cost of placing an order (e.g., for row material stocks) or the set-up cost of production.
The cost of shortage, i.e., what is lost of the stock is insufficient to meet all demand.
The inventory control manager must understand inventory management principles to remain valuable.

P a g e |6First, he must know how much inventory to have on and to ensure continuity of supply in the event of an
uncharacteristic increase in either demand and / or lead time. This quantity of inventory is called the
safety stock.
Second, he must know when to reorder materials for inventory. Generally, this point time is determined
when the quantity of materials in stock decreases to a certain level, called the reorder point.
Third, he must know how much to order.
The solution of all above problems is Economic Order Quantity Model (EOQ)
The EOQ recognizes the tug of war between acquisition costs and inventory carrying costs: when
you order bigger quantities less frequently, your affricate acquisition costs are low but your inventory
costs are high due to higher inventory levels. Conversely, when you order smaller quantities more often,
your inventory expending more resources on ordering. The EOQ is the order quantity that minimizes the
sum of these two costs.
Write a note on ABC system of Stores Control. 2010-June |2|
Answer:ABC concept of classifying goods in an inventory is very commonly used for exercising effective inventory
control. Under this technique, the items in inventory are classified according to the value of usage. The
higher value items have lower safety stocks, because the cost of predictions is very high in respect ofhigher value items. The lower value items carry higher safety stocks.
The annual consumption analyses of any organization would indicate that a handful of top high
Value items, less than 10% of total number, will account for a substantial portion of about 75% of the total
consumption value and such vital few items are called A items. The items falling under this category
require careful attention of bottom items- account for only 10% of the consumption value and are referred
to as C category items. The items that lie between the top and the bottom are referred to as B
Category items. This is explained in the table give below:
Category %of items % of value
A 10 70
B 20 20
C 70 10

Labour AccountingWrite short notes on the following: 2002- Dec, 2004- June, 2010-Dec |8|
(b)Labour Turnover
Answer:Labour turnover (LT): In every organization change of labour takes place. There are many reason ofchange of labour force e. g. to leave for better opportunity, new appointments, sorting of (excess) labour
by organization due to change of technology or recession, etc., this trend of change of labour force from
one organization to another organization is called labour turnover. Labour turn over may be calculated
with the following methods.
Method of labour turnover
Replacement method No. of employees replaced-------------------------------------*100
Average no. of employees no roll
Separation method No. of employees separate during the year--------------------------------------------------------------------*100
Average no. of employees no roll during the period
Flux method No. of employees separated + No. of employees replaced------------------------------------------------------------------------------*100
Average no. of employees on roll during the period

(c)Job evaluation
(e) Incentive to indirect workers
Answer:Job Evaluation:A technique used for determination of net worth of one job with respect to another job.
Thus, it is a process of analysis and evaluation of each job within an organization so that an appropriate
wage and salary structure is ascertained.
Objectives:
Helps employer in understanding worth of one job in comparison to another.
Promotes reliability and equity in designing wage structure.
Helps personnel department in selection and training of employees.
It facilitates cost control.
Use of job evaluation avoids anomalies, confusing and unrest, unrest, which are rampant in
industrial sector
Method job Evaluation: - It can be classified into four groups as following:a. Ranking method:- Jobs are ranked according to their requirements and responsibilities
b. Grading method: - Jobs are rated according in order of their importance.
c. Point ration method: - Jobs are rated according to Responsibility, working conditions, Skill,
Training & Experience, complexity of duty, physical labour and Education.
d. Factor comparison: All jobs are ranked against the key job on the basis of monetary values
assigned to various factors

P a g e |8e. Indirect workers: Those workers which are not directly associated with the conversion of raw
material to indirect workers lead to satisfaction among indirect laborers and increase their
efficiency.
It is essential to provide incentive to indirect labors because of following factors:
They maintain facilities for production which enhances better performance of direct
workers.
Unfair to deprive incentive from indirect workers.
Of incentives are not provided to indirect workers it will lead to dissatisfaction among
them.
Indirect labour can be classified into two groups for the purpose of incentives-
(1) Those which are working witch direct workers such as, supervisors, inspectors, checking staff,
etc.
(2) Those which are providing general service such as, maintenance workers, clerks, peon, keeper,
canteen dispensary staff etc.
Incentives: For the first (1) group incentives is paid as a Percentage of bonus payable to
direct workers or on considering output of departments, etc.Write Short Notes on the following: 2006-June |8|
(e) Accounting of idle timeAnswer:
Idle Time: Idle time is time lost during hours of the organization for any reason e.g. machine break down,
fatigue, tea break, lunch etc. Idle time is classified into two types for the purpose of accounting treatment.
(1) Normal idle time: normal idle time represents inevitable loss of labour hours arising out of given
blow reasons-
Time lost between tea or lunch break, factory gate and concerned department etc.,
Time lost in machine or job setting up time etc.
(2) Abnormal idle time: Time lost due to external causes, which are uncontrollable in the hand ofmanagement e.g.-
Excessive break down.
Power failure
Shortage of material
Strikes and lock out etc.
Treatment of idle time: Normal Idle Time is charged to factory overheads and absorbed into cost of
production adopting absorption an absorption rate. The normal idle time taken for machine setting,
change over or tool setting, can be added to the production cost as direct wages by inflating the hourly
wage rate.
Abnormal Idle Time is charged to Costing Profit and Loss account, Payment of abnormal idle time
cannot be charged to production cost under any circumstances.
Write short notes: 2007-Dec |8|
(d)Learning Curve Answer:The theory of learning curve was introduced by T.P. Wright of U.S.A, when he was manufacturing
airframes. As we know that the definition of learning is to acquire knowledge or ability. Whenever a new
product is started, workers may not be at their full efficiency. But as their experience increases, time taken
to produce the product decreases. This tendency of better performance is known as Learning Curve.

P a g e |9If similar operation talks place, the cost associated with it shows constant decrease. The Learning
Curve is a Geometrical Progression. Cost will increase at a fixed rate and the increase in cost will be at
successively smaller rate.
Average labour cost of first 2 units
Learning curve ration= ------------------------------
Average labour cost of first N units
If the Learning curve ratio is 80%, it means that the average cost will be 80% of previous cost
whenever production doubles.
Learning Curve Equation:
Y x = KXs
Where,
X is the cumulative number of units.
Y is the cumulative average unit cost of those units X
K is the average cost of the first unit and
S is improvement exponent or the learning coefficient or index of learning.
It can be calculated as given under-
Logarithm of learning ratio
S = -------------------------Logarithm of 2

(d) Idle time and Idle capacity
(e) Work measurement and Motion studyAnswer:
(a) Idle Time: Idle is time list during working hours of the organization for any for reason e.g. machine
break down, fatigue, tea break lunch etc. Idle time is classified into two types:
(1) Normal idle time: Normal idle time represents inevitable loss of labour hours arising out of
given blow reason
Time lost between tea or lunch break, factory gate and concerned department etc., Time lost in machine or job setting up time etc.
(2) Abnormal idle time : Time lost due to external causes, which are uncontrollable in the hand of
management e.g.,
Excessive break down.
Power failure
Shortage of material
Strikes and lock out etc.
Idle Capacity: Idle capacity is difference between installed capacity and the actual capacity utilization
when actual capacity utilization when actual capacity utilization is less than installed capacity.
Installed Capacity is the maximum productive capacity according to the manufacturers specification of
machine/ equipment.
Actual Capacity is the volume of production achieved in relation to installed capacity.
Idle capacity represents unused potential by any reason

Incentive to indirect workers and Indirect incentives to direct workers.Answer:
Incentive schemes for workers are made to motivate workers for increasing output land quality
production, saving time, reducing labour turnover and building sense of belonging. Obviously, these
schemes focus on performance of the workers.
While performance of direct workers is easy to measure, that of auxiliary or indirect staff is not.
Accordingly, incentive schemes differ between direct workers, and indirect workers.
Incentive schemes for indirect workers include:
1) Bonus to foremen and supervisors based on output, saving in time, quality improvement,
reduction in scrap, etc.
2) Bonus to repairs and maintenance staff for routine and repetitive jobs, based on reduction in
number of complaints or breakdown.
3) Bonus to stores staff, based on the value of materials handled or the number of requisition per
period.
Indirect incentives to direct workers include:
1) Monetary schemes like profit sharing, co-partnership or co ownership.2) Non, monetary schemes like education and training facilities, health and safety devices, facilities
for sports and housing, subsidized canteen and purchase coupon, pension, creation of sick and
benevolent funds, arrangement of four programs, etc.
What do you understand by computerized payroll? Can it improve labour productivity?
2001-Dec |3|Answer:
Computerized pay roll: It is not possible to maintain all records of employees of manual way like
computation of payroll deduction, disbursement of payments, payroll record of each employee etc. In
large organization payroll accounting has become very difficult to maintain all records of each employee.Now a day they are using computer to keep up to date details of each employee. In large as well as small
organizations have computerized payroll, a database is crested with all permanent details of worker, and
thereafter, information is continuously fed in computer starting form timekeeping and time- booking till
preparation and accounting of payroll.
Computerized payroll has no relation with labour productivity because it is a data base recording system
so it can not improve labour productivity.

Enumerate the principles of a good incentive scheme which should be given due
consideration prior to its implementation. 2002-June |2|
Answer:The objective of wage incentives is to improve productivity and increase production so as to bring
down the unit cost of production. The general principles of a good incentives scheme to be given tobe given due consideration prior to its implementation are enumerated below:
The reward for a job should be linked with the effort involved in the job and the scheme should
be just and fair to both employees and employers.
The standard required of the workers should be carefully set.
The scheme should be carefully define and capable of being understood by the employees
easily. The standards set should be such that they can be achieved even by average employees.
While standards are being set, the workers concerned should be consulted.
The scheme should be reasonable and stable and not is change or modified too often without
consulting the employees.
The scheme should take care that the employees are not penalized for reason beyond their
control.
The scheme should provide for inspection of output so that only good pieces quality for
incentives.
The management should ensure that workers are not sitting idle for want of tools or materials
that is the management has to see that there is, as far as practicable, no interruption of production.
It should be capable of improving the morale of the employees.
There should be guaranteed wage on time bases which generally works as a good
psychological boost to incentive scheme.
The operation of the scheme should not entail heavy clerical costs.
What do you mean by labour turnover? What are the costs associated with it? How
would you treat these costs in cost accounting? 2002-June, 2006-June |2|Answer:(a) Labour Turnover: In every organization change of labour takes pace. There are many reason of
change of labour force e.g. to leave for better opportunity, new appointments, sorting of (excess)

Cost of labour turnover- Cost of labour turnover is of two types:
(1) Preventive Costs: - Those expenses which are incurred to keep the labour force contended so
that excessive labour turnover may be prevented. These costs include the following heads:
-

b. Cost of medical devices (Medical facilities).
c. Employee Development programmed.
d. Pension Schemes
e. Attractive Remuneration.
f. Cost of welfare facilities.
(2) Replacement Costs: - Those expenses which are incurred due to high labour turnover. Main
cause of these expenses is recruitment of inexperience labour force replacing the existing trained
and experience labour force as well as cost includes the following
a. Cost of recruitment, training, and induction new workers.
b. Cost of excessive defective and scrap.
c. Cost of addition supervision required for new labors.
d. Cost of abnormal break ages of tools and machines.
e. Loss of production due to the time leg between separation and in obtaining new labour.
Treatment of labour turnover: - It is generally treated as an overhead expense.
What is idle time? Explain the causes for idle time. 2008-Dec |2|
Answer:Idle Time: Idle Time is that time for which payment made but no direct production /benefit is obtained. The
question of Idle Time arises only when the payment is made on time basis. It is calculated as follows:
Idle Time: Time Recorded as per Time card- Time Booked on Job as per job card.
Idle time may arise due to any one or more of the following causes.
1. Production causes:
a. Machine Break Down
b. Power failures
c. Waiting for work
d. Waiting for Toolse. Waiting for Materials
f. Waiting for Instructions
2. Administration causes (which arise due to administrative decisions)
a. Decision not to retrench regular trained workers in the period of depression
b. Decision not to work up to full capacity of plant.
3. Economic causes (which arise due to economic conditions & decisions) Closure of seasonal
industry during offseason.

OverheadWrite short notes on the following: 2002-Dec |8|
(a)Administration overheads
Answer:Administrative Overhead- It is cost of directing, formulation of policy, controlling the operations of anenterprise and management of affairs. It is not related directly to production, selling & distribution function.
For example salary, legal fee, cost of printing & stationery, rent rants & taxes of building, telephone
expense, etc.
(1) Accounting of administration overheads:
Apportioning Administration overheads between production and sales Departments.
Administration overheads are charged to Profit and Loss A/c.
Administration overheads are treated as a special addition to cost of production or sales.
(2) Control of Administration overheads: there are three methods for control of administration
overhead as follows-
Write short notes on the following: 2006-Dec |8|(b)Method for disposal of under/over-absorbed overheads
Answer:Method of disposing under/over absorbed overheads: The following method are often used for
disposition of under/ over absorbed overhead-
Write off to profit and loss account- Under this method, amount of under or over absorbed overhead is
transferred to the costing profit and loss account. This method is application when the amount is not
significant in relation to the total overheads.
Carry forward to the next Accounting Period- Under this method , amount of under/over absorbed
overhead is carried over to the next occurred due to the seasonal fluctuation and business cycle which
extend over more than one years.
Use of Supplementary Rates- When the amount of under or over absorbed is significant this method is
used. Under this method, accounts are brought to an actual cost basis so far as overhead is concerned.
The supplementary is calculated to adjust the amount of under or over absorbed in the cost of work in
progress, finished stock and cost sales.

(a)Depreciation and Obsolescence
(e)Cost allocation and Cost appropriation
Answer:(a) Distinguish between Depreciation and Obsolescence:-
Depreciation is the decrease in the value a fixed asset due to use or wear and tear and / or laps
of time. Whereas Obsolescence is the loss in value of an asset due to technology, change in the
product or method of manufacturing.
It is recovered by adopting suitable is considered as loss of asset value.

P a g e |15 It absorbed into cost of product on some equitable basis. Whereas Obsolescence cannot be
absorbed into cost of product.
Depreciation is provided for the purpose of replacement of the asset at the end at the end of its
useful life on periodic basis. Whereas Obsolescence is not provided of the asset because it may
occur once in the life.
Depreciation charging rate are given and charged as per provision. Where as a company may
make separate provision for obsolescence loss or written off as loss in full or on deferred basis.
(e)Cost allocation and Cost appropriation:-
Allocation deals with whole items of cost, apportionment deals with proportion items of cost.
Allocation is direct process but apportionment may be made only indirectly and for which suitable
bases are to be selected.
In allocation overheads are allocated but in apportionment allocation overheads are not
allocated.

Profit for incomplete contracts: those contracts which cannot be completed within the same financial year
or which take more than one year are called incomplete contract. In these contracts a problem arises
profit on such contracts should be considered on the completion of the contract or at each financial year
on the partly completed work. Contract or at the end of each financial year on the partly completed work.
If we compute profit at the end of completion of work, profit will be high in the year of completion of the
contract, where in other years working on contract, profit will be nil. Therefore when contact takes more

performed during the year. There are no hard and fast rules for computing the figures of profit to be taken
to the profit and loss account in case of in completed contract. However the following rules may be
followed in this account-
(a) If work certified is less than 1/4th
of the contract, on profit is calculated.
(b) If work certified more then 1/43rd
of the profit is transferred into profit and loss account. The
balance is treated is treated as reserve.
(c) If work certified more than half but less than 9/10 (still not in final stages) of the contract price,
then 2/3rd
of the profit is transferred into profit and loss account is computed as follows:
Profit transferred to P&L Account= 2/3 * notional profit* cash received/work certified
The balance is treated as reserve.
(d) When contract is almost complete, an estimated profit should be calculated on the whole
contract. The portion of this estimate profit to be profit & account.
Write short notes on the following: 2004-Dec|8|
(d)Batch costing;
(e) Cost-plus-contract
Answer:It is an extension of job costing. Under this method of costing products are standardized and process are
repetitive. The most important criterion of batch is to determine the economic or optimum batch size or
quantity. All costs are collected by batch order number and total costs are divided by total number of
products produced in a batch to arrive at average unit cost of production.
It is used in toy making industry, radio and T.V. parts producing industry, watch making industry, etc.
Advantages:
It helps in the reduction of cost as units/goods are purchased in batches.
Economic batch quantity =
Where,A=Annual demand
S=Set up cost per batch
C=Cost of storing one unit p.a.
(e) Cost price is ascertained after adding up a percentage of profit to total cost of work. CIMA defines
Cost plus contracts as one where the contractor is reimbursed allowable or otherwise defined
cost plus a percentage of these costs or fixe fee towards profit. In other words contractee
undertakes to reimburse the actual cost plus a stipulated profit. The cost to be assed to cost may
be either a fixed amount or a specified percentage of cost. Cost plus contract generally are
usually entered into during emergency such as war when there is no time to go through proper
channel of contract. This method is also used when to is not possible to compute the cost of work
in advance with reasonable degree to compute when there is unstable condition of market prices
(during fluctuation of market prices )labour rate etc.
Advantages:
(i) The contractor is sure of a fixed profit .
(ii) There is no risk of loss on such contract.
(iii) As the customer, contractor con not exploit him.
(iv) Useful when work to be performed is not fixed.
Disadvantages:

P a g e |18(i) In such contracts, contractee has no clear idea of his liability until after completion of
contract.
(ii) The contractor is deprived of the advantages which would have accrued due to favorable
market condition.
(iii) Contractor is tempted to increase the cost because greater the cost, greater will be his
share of profit.
Contact works may be at different stages of completion at the end of an accounting period.

works.2002-Dec |4|
Answers:In these contracts a problem arises profit on such contracts should be considered on the completion of
the contract or at the end of each financial year on the partly completed work. If we compute profit at the
end of completion of work, profit will be high in the year of completion of the contract, where in other
years working on contract, profit will be nil. Therefore when contact takes more than one year, it
becomes necessary to take in to account the profit earned or loss incurred on the work performed during
the year. There are on hard and fast rules for computing the figures of profit to be taken to the profit to theprofit and loss account in case of incomplete of profit to be followed to compute profit in respect of such

Write short notes on the following: 2002-June |8|
(c) Equivalent production
Answer:Equivalent production is a technique of presenting production of process in terms of completed units. This
concepts is used for assigning cost to process to both finished units and unfinished units. This technique
is used in process industries where production takes place on a continuous basis; there is a problem of
valuation of work in process at the end of accounting year. These units cannot be treated as completed
units and cost incurred is only apportioned on completed units. Thus, these units are converted into
equivalent units. Equivalent unit as defined by CIMA is notional whole units representing completed work
used to apportion costs between work I process and completed output
Equivalent completed units= (No. of units in work in process * Degree of completion in %)
For Eg: if closing stock is 5,000 units 100% completed in respect of material and 50% in respect of labour
& overheads.

(e)Concept of split-off point and joint cost.
Answer:Split off point: This is a point up to which input factors are commonly used for production of multiple
production, which can be either joint products or by products. After this point joint products and byproducts gains individual identity.
Joint Costs: Join are those costs which are common to the processing of joint products up to the point of
separation. Joint costs represent pre-separation cost of joint products or by products. After the point of
serration, the products can be separately identified and post separation costs can be readily attributed to
individual products.

Answer:Reserves Cost Method in By Product cost accounting: whereby products are of considerable sale
value. The profitgained from the by-product should not be credited to Process Account. Under this
method, selling price or by product up to the split-off point will be debited to a byproduct account and
credited to the main product account.
Under this method, the sale value of by () is first reduced by-

Explain the impotence of Equivalent production in process costing. 2007-Dec|2|
Answer:Importance of equivalent production in process costing:
Work done in process is represented by competed units as well as partly finished units. The difficultarises in allocating the cost, when work done is expressed both in terms of finished units. The concept of
Equivalent units is introduced to overcome with this problem. Equivalent production is a technique by
which work done on unfinished units is expressed u terms of completed units only. This technique is to
find out units, which would have been completed, if the work done on unfinished units had been done for
finished units only.
State the fundamental principal of process costing. 2009-June |3|
Answer:Fundamental Principles of Process Costing:
Individual units losses their identity
Cost of each process should be ascertained and should be transferred to next process.
Production should be uniform and should be in continuous flow. Incompletely units are taken as equivalent complete units for computing unit cost.
Cost of normal loss is apportioned on fair units and cost of abnormal loss is ascertained
separately and credited to process a/c.
Cost of normal loss is changed to costing P/L a/c

RECONCILIATION OF COST AND FINANCIAL ACCOUNTS
Explain the need for reconciliation of cost and financial accounts. Also state the reasons for
difference in profit between the two accounts. 2009-June |7|
Answer:In Non-Integral System where separate sets of books are maintained for costing and financialtransactions, the profit shown by one set of books may not agree with of the other books because these
two sets of books may follow different accounting principle and policies.
Hence, the need for reconciliation of cost and financial accounts arises:
1. To identify the reasons for the difference between the results shown by the Cost Accounts and
Financial Accounts.
2. To check the arithmetical accuracy and reliability of both the sets of books
It may also be noted that financial accounts and cost accounts when maintained on a Computer system,
may show accurate and precise result but even then the profit shown by one set of books may not agree
with that of the other set. Thus, under the situation of difference between the results shown by both the
sets of books, the reconciliation is essential and not redundant event in the modern of age of computer.

All costs are divided into two components i.e. variable and fixed costs.
Variable cost per unit remains constant
Total fixe cost remains constant
There is only one product or if there are multiple products the product mix does not change
Selling price per unit remains constant
Productivity per worker remains constant
General price level remains fixed
Write short notes on the following: 2004-June |8|
(a)Differential cost analysis(b)Angle of incidence
Answer:Differential cost analysis: CIMA has defined Differential Costing as a technique used in the
preparation of ad-hoc information in which only costs and income difference between alternatives
calculations includes both variables and fixed costs which are affected by the alternative courses of
action.
Uses of DCA
Introduction of new product.
Opening up of new product distribution channel.
Acceptance of export order requiring additional outlay. Acceptance of addition order at lower price to special customers.
Processing of by product or joint product price to special customers.
Processing of by product or joint product beyond split off point.
(b)Angle of incidence: when sales line and total cost line intersects at breakeven point, angle of
incidence is formed. It gives pictorial relationship between profit and sales. The wider the angle, greater is
the rate of earnings of profit. Therefore, a management always aims at a large angle of incidence.

(a)Application of marginal costing to price fixing
Answer:Application of marginal costing to price fixing: Normally, prices are regulated by demand and fixation of
the selling price should be fixed in such a manner that it covers the total cost and some of profit is alsoearned form it. But under certain conditions such as depression, a firm has to sell its product below total
cost. Under such conditions a firm should price its product above its marginal cost so that contribution is
made towards fixed costs which will reduce losses that will be incurred if production is stopped.
Marginal costing helps management in decision making i.e. making best choice amount various
littermates. Following are some of the decisions which are taken with the help of marginal costing:
Fixation of selling Price
Make or buy decisions

(a)Sensitivity Analysis
(b)Relevant Cost
(c) Cost plus Pricing
Answer:Sensitivity Analysis: Sensitivity Analysis is a technique to determine how different values of
independent variable affect the value of dependent variable under a given set of assumption. Sensitivity
Analysis is a way to predict the outcome of a decision if a situation turnout to be different compared to theprediction.
For example, an analyst might create a financial model that will have a companys equity (the dependent
variable) given the amount of earnings per share (an independent variable) the company report at the end
of the year. The analyst can create a table of predicted price-to-earnings multiples and a corresponding
value of the companys equity bases on different values for each of the independent variables.
Sensitivity Analysis is used
To simplify models.
To investigate the robustness of the model predictions.
As an element of quality assurance.
However there are some problems associated with Sensitivity analysis in the business e.g.
Analysis in the business e.g.
Variables are often interdependent, which makes examining them each individually unrealistic.
Generally the assumption upon which the analysis is based are made by using past data which
may not hold true in the future.
(b) Relevant cost: Every business decision involves planning for future and considers several
courses of action. During this process of decision making any cost which affected by decision are
future costs which are known as relevant costs.
(c) Cost plus pricing: cost-plus pricing is a strategy that is used to determine the retail and/or
wholesale price of goods and services. Businesses of all sizes tend to use this simplistic pricing

7/30/2019 Costing Thory
27/64
P a g e |27model as a guideline for arriving at sale prices that will allow the company to cover all costs
associated with the production and sale of the products, and still make a reasonable profit. Cost-
plus pricing works for calculating pricing goods such as the cost of a meal in a caf and pricing
services such as utilities or courier services.
The ultimate goal of cost-plus pricing is to allow, to price goods and services and covered
in a manner that helps to ensure all costs associated are covered. At the same time, cost-plus
pricing helps to profit and remains competitive with companies that offer similar goods and
services.
Components to calculate cost plus pricing:
The first key component to calculating cost-plus pricing is to establish key with is costs to
actually produce the end product or service.
Next, there is the matter of determining the additional price to attach to each unit offered for sale.
Another factor that will influence the percentage markup is local competition.
However, a simple twofold approach is often workable for small businesses, provided all
expenses associated with the production and delivery of the finished goods or services is
accounted for in the unit cost.

(e) Marginal costing for decision making.
Answer:Marginal costing for decision making:
Making costing is a technique frequently used for short-term decision-making. During a short period
variable costs may vary in proportion. To output, whilst fixed cost remain static. Marginal contribution is
the difference between sales and variable costs. It increases at a fixed rate (per unit basis) as the output
increases, increases, up to the optimum production level. So, the primary objective of an enterprise
during a relevant short period will be to produce up to the attainable capacity. For, period to the BEP level
of production fixed costs eat into the marginal contribution, but there after any marginal contribution will
be the net profit. Marginal Costing technique helps short-term decision making in the following areas:
Profit planning and selection of product-mix
Problems of limiting factor
Performance evaluation
Fixation of selling price and quoting for tender
Additional order at home or for going global
To make or buy
Alternative methods of manufacture
Outsourcing or sub-contracting
Suspending activities or fixing time to close down.

P a g e |28These three factors are inter-connected in such a way that they act and react on one another because of
cause and effect relationship between them. The cost of a product determines its selling price and the
selling price determines the level of profit. The selling price also affects the volume of sales which directly
of production and volume of production in turn influences cost. In brief, variations in volume of production
results in changes in cost and profit. CIMA London has defended CVP analysis as the study of the
effects on future profits of changes in fixed cost. Variable cost, sales price, quantity and mix.
An understanding of CPV analysis is extremely useful to the management in budgeting and profit
panning. It explains the impact of the following on the net profit:
Changes in selling prices,
Changes in volume of sales,
Changes in variable cost and
Changes in fixed cost.
Infect, CVP analysis helps in determining the probable effect of change in any one of these factors on the
remaining factors.

(a)Mention a few cases where products may be sold below variable cost.
(b)What are the assumptions of Break-even Analysis?
Answer:The Cases where products may be sold below variable cost are given blow-
1. When goods cannot be stored for a long time.
2. To increase the sale in the market.
3. For publicity sale of limited quantity for limited period.
4. When a weaker competitor is to be driven out of market.
5. When a weaker competitor is to driven out of market.6. When plant should be kept ready for full production ahead.
7. When future market is uncertain.
8. When the sale of one product will push up the sales of other conjoined profitable products
(b) Assumption of Break even Analyses are given below-
(i) Fixed cost will remain constant at various levels of activity.
(ii) Variable cost per unit and sales units is equal and no inventory.

P a g e |30(iii) Production units and sales units are equal and no inventory exists in beginning or at the end of
the period for which analyses made.
(iv) Productivity, operating efficiency, product specification will not change.
(v) Total cost and total revenue can be represented in straight lines.
(vi) There will not be any change in pricing policy due to change in volume, competition, etc.
(vii) Creak-even analyses competently ignore the capital employed in business, which is one of the
important facts in determination of profitability of the company and its products.
(viii) Cost should be segregated into fixed and variable components.
All these assumption are not always true. For example-
a. Fixed cost cannot be fixed in long run.
b. There is difficultly in segregation of semi variable expenses into variable and fixed elements of costs
accurately.
c. It is most likely that increase/ decrease /decrease in sale price may have some impact on unit sale
price

What is profit Volume Ratio? Mention some possible course s of action to improve this
ratio. 2003-June |5|Answer:Profit volume ration is actually the ratio of contribution earned to sales made. This is also known as
contribution margin ratio. Better P/V ratio is an index of sound financial health of a companys product
P/V ratio establishes the relationship between contribution and sales. It is also known as contribution/
sales ratio.
P/v ratio =

Improvement of profit Volume Ratio: P/V ratio can be improved by the following possible course of action.
By increasing selling price
By reducing the share of low margin product in the total sales
By changing sales mix
What are the important applications of marginal costing as a tool for decision making?
2003-Dec |5|
Answer:The important application of marginal costing- Marginally cost is essentially a technique of decision-
making. In the following situation marginal costing is useful in managerial decision making.
Profit planning
Key factor analysis
Contribution analysis
Optimizing product mix
Make or buy decision Price fixation
Alternative use of production facility
Evaluation of performance
Break even analysis Cost volume analysis
Presentation of cost data for control purpose etc.
From above we can say in every field marginal costing is a tool for decisions making
Product pricing is an important area for management decision making. State very brieflythe broad objectives of the pricing policy. Mention specifically situations prices are fixed are
fixed below the variable cost. 2004-Dec |5|
Answer:Pricing is a profit planning exercise in which management searches out the alternatives in an effort to
choose one alternative which is the most advantageous alternative Pricing decision plays a very
important role by assisting the management in the evaluation of profit arising out of various
alternatives.
Objectives of the Pricing Policy:
Objective of pricing policy should be in conformity with overall organizational objective. Maximization
of profit is the main objective of any organization but it should not only the objective of any
organization but it should not only the objective of any organization.
The other objectives of pricing policy are as follows:
Pricing the goods bases on reasonable basis.
Immediate survival of the firm.
To safeguard against the emergence of new producers in the same line.
Increase in the market share or its growth rate at the expense of profit.

P a g e |32 Avoid adverse public reaction consequent on charging high price.
Situation where prices are fixed below the variable cost:
When goods cannot be stored for a long time.
To increase the sale in the market.
For publicity sale of limited quantity for limited period.
When a new product is introduced in the market or to popularize it.
When a weaker competitor is introduced in the market or to popularize it.
When a weaker competitor is to be driven out of market.
When plant should be kept ready for full production ahead.
When future market is uncertain.
When the sale of one product will push up the sales of other conjoined profitable products.
What is profit volume graph? Explain how it is drawn. What are its important limitations?
2007-June |5|
Answer:P/v Chart shows the relationship between profit and sales volume. It is a simplified form of break even
chart. The horizontal axis on P/v Chart represents the sale volume and vertical axis represents the
profit/loss and fixed cost. The point at which sales line intersects the profit line is known as breakeven
point.
Steps for preparation of P/V graph/ Chart A scale of sales on horizontal axis is selected.
A scale of profit and fixed cost on vertical axis is selected
Horizontal axis is divided into 2 parts
Lower-fixed cost Upper-Profit Profit, fixed cost and sales volume are plotted
Lower-loss area Upper- Profit are a Vertical axis is also divided into2 parts
Points are joined to form a line called profit line
Point at which profit line intersects sales line is known as break even points.
Angle which profit line makes with sales line is called as angle of incidence.
Sales volume beyond breakeven point is called is margin of safetyLimitations:
a. Assumes constant selling price and the same pattern of sales amount different products
b. Change in inventory levels at the beginning and end will be insignificant.
c. It assumes the same level of technology and efficiency.
What are the factors those are taken into account by the management while considering a
Make or Buy decision? 2009-June |4|
Answer:Whether a component is to be manufactured or purchased from outside supplier is decided is decided by
comparing the marginal cost of manufacturing with the market price of the component. Specific and
additional fixed cost may be treated as relevant cost. If the factory is operating at full capacity, thendecision is taken after adding opportunity cost of production. In addition to above, following factors are
also taken into consideration.
a. Plant capacity
b. Profit maximization
c. Specialization
d. Nature of product
e. Secrecy

ACTIVITY BASED COSTING
Write short notes on the following: 2002-Dec |8|
(a)Activity-Based Budgeting
Answer:Activity Based Budgeting:
Definition: Activity Based Budgeting is panning and controlling activities and cross functional business
processes of an organization. Activity Based Budgeting stands in contrast to traditional, cost-based
budgeting practices in which a prior periods budget is simply adjusted to account for inflation or revenue
growth. As such, ABB provides opportunities to align activities with objectives streamline costs and
improve business practices. ABB is a method of budgeting in which activities that incur costs in each
function of an organization are established and relationships are defined between activities. This
information is then used to decide how much resource should be allocated to each activity. Basically,
ABB is budgeting by activities by activities rather than by cost elements.
Features of ABB:
Supports Perpetual Planning.
Engage everyone in thinking about how they can better create value for organization.
Line planning and activity based budgeting.
Budget activities and cross functional business processes to strategy and corporate goals.
Identify waste and non-value in budget and create action plans to eliminate it.
Forecast workloads to create activity based budget.
Charge out service departments (MIS, H/R, and accounting) to operating departments.
Incorporated financial and non-financial alternatives into the budgeting process.
Develop a fixable budget based on activity work load.

I. Activity base management
Answer:Activity Based Management (ABC): is a discipline that focuses on the management of activities as ways
improve customer value and profit. ABM included cost driver analysis, activity analysis, and performance
measurement. Increasing competition, both globally and locally, make it clear that businesses know

P a g e |34accurately and understand the source of process, product and service costs within their organization.
Activity Bases Costing (ABC), with its focus on deconstructing overhead pools and assigning costs to
products and services in a more meaningful manner, has been a giant leap forward from traditional
costing models where a high percentage of cost is arbitrarily allocated to products.
However, ABC Model often look at cost from a financial point of view, making sure only that all
costs are assigned to some product accounting box without a thorough understanding of the business
process that underlies and defines the resource utilization that creates the cost. The methodology that
combines business process analysis with ABC to create a tool that translates Activity Bases Costing into
Activity Based Management (ABM).

(b)Activity Based Costing
Answer:Meaning of Activity Based Costing
Activity Based Costing (ABC) is a technique of charging overheads to cost objects (i.e., products,
services, jobs, customers etc.)Under which overheads are first calculated separately for each activity andthem are charged to various cost objects on the basis of activities consumed by these cost objects.
According to Cooper and Kaplan, ABC system calculates the costs of individual activities and assigns
costs to cost objects such as products and services on the basis of activities undertaken to produce each
product or service.
CIMA, London, defines activity based costing as Cost attribution to cost units on the basis of benefits
received from indirect activities, i.e., ordering, setting up assuring quality etc.

(c) Cost Driver;
Answer:Cost Drivers: Direct labour and materials are relatively easy to trace directly to products, but it is more
difficult to directly allocate indirect costs to products. Where products use common resources differently,
some basis is needed in the cost allocation process. The measure of the use of a shred activity by each
of the products is known as the cost driver. For example, the cost of the activity of bank tellers can be
ascribed to each product by measuring how long each product by measuring how long each product by
measuring how long each products transaction takes at the counter and then by measuring the number
of each type of transaction.
Explain the concepts of Activity based costing and cost drivers. 2003-Dec |7|
Answer:Activity-Based Costing (ABC) is a costing model that identifies activities in an organization and assigns
the cost of each activity resource to products and services. In order to correctly associate costs with
products and services, ABC assigns costs to activities based on their use of resources.
In a business organization, the ABC methodology assigns an organizations resource costs through
activities to the products and services provided to its customers.
It is generally used as a tool for understanding product and customer cost and profitability.
